The 'boring-expansion' set of proposals that I made back in 2022, with the help of Google Fonts and industry colleagues, have finally become part of the new ISO Open Font Format 5th edition international font format standard. It _only_ took four years...

PDF can be downloaded for free, albeit after a checkout process and watermarked to the individual.
